T0 61/ whom it may concern:

Be it known that I, WILLIAM B. BROSIUS, a citizen of the United States, residing in the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Pallet Setting and Adjusting Tools, of which the following is a full, clear, and exact description.

My invention relates to a pallet setting and adjusting tool which is adapted for use in setting and adjusting the pallet-stones of watch-escapement pallets; and the object of my invention is to provide a simple inexpensive tool for adjusting the pallet-stones of straight-line or parallel pallets or any exposed pallet.

A further object of my invention is to provide a simple tool whereby either arm of a pallet may be heated in order to properly set its pallet-stone without affecting the opposite arm.

To the above purposes my invention consists in certain novel features of construction and arrangement of parts that will be herein after more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which Figure 1 is a perspective view of a pallet setting and adjusting tool of my improved construction. Fig. 2 is an enlarged plan view of the forward end of my improved tool and showing a pallet in position thereon. Fig. 3 is a plan View analogous to Fig. 2 and showing the pallet of a parallel escapement in position on the tool. Fig. 4 is a side elevation, partly in section, of the forward end of a spring-actuated finger made use of in my improved tool. Fig. 5 is a transverse section taken on line 5 5 of Fig. 3.

Referring by numerals'to the accompanying drawings, 1 designates the handle of my improved tool, with the forward end of which is formed integral a spring-ring 2, and

formed integral with and extending forwardly from this ring is apair of arms 3, which are provided at their outer ends with integral plates 4.

Pivotally mounted on top of the arms 3 at points approximately midway between the ring 2 and the plates 3 are the adjusting-fingers 5, which are preferably provided with the tapered rear ends 6, which terminate in points 7. The forward ends 8 of these fingers 5 are formed on diagonal lines, so as to provide inclined faces that extend upwardly from the top surfaces of the arms 3, and the left-hand one of the fingers has its front face formed at a greater angle than the front face of the opposite finger, this being essential in order to corres 0nd to the position of the pallet-stones carried by the pallets.

Secured to the under side of the right-hand arm 3 is a downwardly-projecting pin 9, in which is formed a horizontally-arranged aperture 10, and passing therethrough is a screw-shaft 11. This shaft 11 is provided with an enlarged end 12 outside the pin 9, and said enlarged end is provided with an inte'gral disk 13, that is to be engaged in manipulating the screwshaft 11. The opposite end of this screw-shaft is threaded and passes through a correspondingly-threaded aperture 14 in a pin 15, that extends downwardly from the opposite arm 3. Located upon the shaft 11 between the pins 9 and 14 is a short sleeve 16. The spring-ring 2 is so constructed as to normally throw the arms 3 apart, and the screw-shaft 11 is utilized for bringing said arms together when a pallet is being adjusted.

Fixed to and extending upwardly from the forward end of the handle 1 adjacent the ring 2 is a post 17, the upper end of which is slotted in order to receive the rear end of a finger 18, that is pivotally held in said post, and the rear end of said finger being provided with an integral handle 19, that is positioned directly over the handle 1. A leaf-spring 20 is secured to the handle 1 adjacent the post 17 and the free rear end of said spring bears against the under side of the handle 19. Formed integral with the forward end of the finger 18 is a downwardly-projecting pin 19, in the under side of the lower end of which is formed a recess 20.

The use of my improved tool is as follows: In adjusting and setting the pallet-stones of a pallet 'for a straight-line escapement the curved arm A of the pallet, which carries the stones B in its outer ends, is positioned on top of the arms 3 immediately in front of the inclined vertical faces 8 at the forward ends of the fingers 5 and with the fork O of said pallet extending forwardly between the plates 4. The forward end of the finger 18 has previously been elevated by depressing the handle 19, and after the pallet is in position, as seen in Fig. 2, the forward end of the finger 18 is allowed to move downwardly, so that the lower end of the pin 19 engages the upper end of the pivot-pin D, that projects upwardly from the center of the curved arm A. Thus the pallet is maintained in position upon the arms 3 by the spring-pressed finger 18, and when so positioned the stones B can be adjusted forwardly or out of their recesses by moving them outwardly with a suitable pointed tool, or they can be moved rearwardly in their recesses by engaging the tapered rear ends 6 of the fingers and swinging said fingers upon their pivots so that the forward ends thereof bear against the outer ends of the pallet-stones and move them rearwardly.

It very often happens that one of the pallet-stones becomes loose and out of proper position and it is desired to readjust and set the same. Said stone can be very quickly adjusted by the use of my improved tool, as just described, and after it has been moved inwardly or outwardly to the proper position a minute quantity of shellac or other adhesive substance is applied to said stone, and then by heating the plate 4 of the arm 3, on which this particular pallet-stone rests, the shellac or other adhesive substance will flow and set in and around the palletstone, and thus very rigidly maintain said stone in proper position. The heat thus applied to one of the stones and on one side of the pallet does not affect the opposite stone, and for this reason each stone can be independently adjusted and set. In Fig. 3 I have shown the pallet of a parallel escapement, and when the pallet-stones of this form of pallet are adjusted and set the heads of the screws that pass through the pallet are positioned between the arms 3, while said pallet is held by the tool.

A tool of my improved construction is very simple, inexpensive, comprises a minimum number of parts, and can be very advantageously used in adjusting and setting the al let-stones of all forms of exposed pal ets. The particular advantage gained by the use of my improved tool is that either stone may be adjusted and set by heating the adhesive without affecting the correct position of the opposite stone.

I claim- 1. In a pallet setting and adjusting tool, a handle, a pair of arms integral therewith, and means whereby a pallet is held upon said arms, substantially as specified.

2. In a pallet setting and adjusting tool, a handle, a pair of arms integral therewith, a plate integral with each arm, and means whereby a pallet is held in position upon said arms, substantiallyas specified.

3. In a pallet setting and adjusting tool, a handle, a pair of arms integral therewith, adjusting -fingers pivotally mounted on said arms and means whereby a pallet is held in positon on said arms in front of the fingers, substantially as specified.

4. In a pallet setting and adjusting tool, a bifurcated handle, adjusting -fingers pivotally arranged on the arms of said handle, and means whereby a pallet is held in position with one end on each arm in front of the fingers, substantially as specified.

5. In a pallet setting and adjusting tool, a bifurcated handle, plates integral with the arms of said handle, adjusting-fingers pivotally mounted on the arms, and means whereby a pallet is held in position on the arms in front of the fingers, substantially as specified.

6. In a pallet setting and adjusting tool, a bifurcated handle having spring-arms, means whereby said arms are drawn together, adjusting-fingers located on the spring-arms, and means whereby a pallet is held in position on said arms in front of the fingers, substantially as specified.

7.
